Background technique
Outdoor terminal box is one of important equipment of substation, is outdoor electrical equipment and indoor observing and controlling, protection, communication etc.
The intermediate link of equipment connection, is generally mounted on by equipment on the spot.Usually it is all opening door, but if the chamber door of the case is close
Feng Buyan causes humid air or rainwater to enter, insulation against ground resistance in direct-current secondary circuit will be caused to decline, serious person's insulated electro
Resistance drops to zero, to form DC earthing, if forming direct current two points ground fault, can constitute ground short circuit, cause relay
Protection, signal, automatic device malfunction or tripping, or DC insurance is caused to fuse, lose protection and automatic device, control loop
Power supply seriously threatens electric power netting safe running.Therefore it is required that terminal box chamber door has good sealing performance, waterproof and dampproof function is realized
Energy.
In substation's maintenance work, as Outdoor Terminal Case service life increases, the corrosion of terminal box chamber door, deformation, very
It breaks down to chamber door handle, causes chamber door that can not shut or poorly sealed, external humidification air is easily accessible in case；It meets under blowing
When the bad weathers such as rain, poorly sealed chamber door itself is easy to be scraped off by wind, so that terminal box internal circuit is soaked with rain, easily
Cause equipment short circuit grounding.When inspection personnel has found such defect during O&M at present, maintenance teams and groups is being waited to handle it
Before, it is general first temporarily to block chamber door with brick, or chamber door, but these methods are bundled using objects such as cotton rope, iron wire or scrap electrical wires
It is different to bundle elasticity, and is not easy to meet terminal box air-proof condition.Therefore, it is badly in need of one kind and is applicable to different size terminals casees
, be able to satisfy its air-proof condition be fixed temporarily tool.
Utility model content
Different size terminals casees are applicable to the technical problem to be solved by the utility model is to provide one kind and are had portable
The terminal box chamber door temporary fasteners of property and security reliability.
In order to solve the above technical problems, the technical solution of the utility model is: a kind of terminal box chamber door temporary fasteners, packet
Cross bar and movable lever are included, one end of the activity lever is slidably connected on cross bar and is provided with fixed device, movable lever
Quantity be two or more, U-shaped arrangement between cross bar and any two movable levers.
It is further: the concrete form being slidably connected between movable lever and cross bar are as follows: the one of movable lever
End is provided with sliding sleeve, and the sliding sleeve is placed on cross bar.
Further: the cross bar is square tube with sliding sleeve.
Further: the fixed device is one of screw thread pair top-fastener, rack gear detent mechanism and bolt.
Further: described cross bar one end is provided with stud, and the other end is provided with the screw hole matched with the stud.
Further: the side of the activity lever is provided with fixing clip, and the outer layer of the fixing clip is elastomer.
Further: the side of the activity lever is provided with movable clip block, and the outer layer of the movable clip block is elastomer,
Its internal layer is connected with fixture block and adjusts bolt, and fixture block adjusts bolt and passes through screw thread pair connection activity lever.
By using above technical scheme, the utility model has the following beneficial effects:
1. this programme is by being arranged on cross bar moveable two movable levers, so that the present apparatus is suitable for different sizes
Terminal box width.Additionally due to being removably to be slidably connected between movable lever and cross bar, so that each main component of the present apparatus
It is removable to separate, occupied space is reduced in transport carrying process, there is portability.Additionally by consolidating on setting activity lever
Determine device, so that the effect being fixedly clamped is firm, functional reliability is high；And the terminal chamber door damaged is reliably solid due to obtaining
It is fixed, improve device security.
2. the cross bar of this programme and sliding sleeve can be square tube, so that circumferential turn will not be generated between movable lever and cross bar
It is dynamic, improve equipment dependability.
3. the cross bar of this programme is by being arranged corresponding stud and screw hole at both ends, so that cross bar can be connected with multistage connecting,
The present apparatus is further improved to the adaptability of different size terminals case width.
4. the settable fixation of this programme or movable clip block, especially the outer layer of fixture block be elastomer so that the present apparatus is being pressed from both sides
It holds during fixing, on the one hand will not destroy the appearance top coat layer of terminal box, on the other hand make the clamping friction of the present apparatus
Power increases, so that it is not easy to slip, increases functional reliability.
5. this programme is by being arranged adjustable movable clip block so that the present apparatus to the adaptability of different size terminals casees into
One step is promoted, and can directly be pressed to the terminal box surface to be clamped additionally, due to bolt is adjusted, clamping force be improved, so that this dress
The functional reliability set further is promoted.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Wherein 1- active retaining rod, 2- screw hole, 3- movable sleeve, 4- lever adjust bolt, 5- cross bar, 6- stud, 7- fixture block tune
Save bolt, 8- movable clip block, 9- fixing clip.
Specific embodiment
It is further elaborated below in conjunction with a kind of preferred embodiment of the attached drawing 1 to the utility model.
The terminal box chamber door temporary fasteners of this preference, including cross bar 5 and movable lever 1.Cross bar 5 is 40cm*4cm*
The stainless steel square tube of 4cm, square tube one end are welded with M20 thread bush, and the other end is welded with M20 stud.When in use, two cross bars
It can interconnect.The stainless steel square tube that the activity lever 1 is 30cm*4cm*4cm, one end are welded with 4.5cm*4.5cm*
The sliding sleeve 3 that the square tube of 0.2cm specification is made into.When in use, sliding sleeve 3 can be inserted in from one end of cross bar 5.For general case
Door, it is only necessary to 2 movable levers 1, but under special circumstances, the quantity of movable lever 1 can be increased.
Fixed device 4 is provided on sliding sleeve 3, the fixation device 4 of this preference is screw thread pair top-fastener, is specially existed
